Plugin Proposal: AgentID — Cryptographic Identity & Trust Layer for ElizaOS Agents

[haroldmalikfrimpong-ops]

Summary

AgentID provides cryptographic identity, trust levels, and blockchain receipts for AI agents. Proposing an @elizaos/plugin-agentid integration.

Why This Fits ElizaOS

• Ed25519 native — AgentID uses Ed25519 keys, same as Solana. Agent's identity key IS a Solana wallet address.
• Agent-as-wallet — register an agent, automatically get a Solana address. Hold funds, send/receive stablecoins.
• Trust levels (L0-L4) — automatic promotion/demotion based on verification history. Spending authority gated per level.
• Challenge-response — real-time proof of key ownership. Stops impersonation.
• Behavioural fingerprinting — detect when an agent acts unusual (frequency spikes, unusual hours, new actions).
• Dual receipts — every action gets both a hash receipt (HMAC-SHA256) and a Solana blockchain receipt.
• Multi-chain — Solana, Ethereum, Polygon wallet binding.

What the Plugin Would Provide

• Auto-register ElizaOS agents with AgentID on startup
• Verify other agents before interaction
• Trust-gated actions (only interact with L2+ agents)
• Blockchain receipts for every agent action
• Built-in Solana wallet from the agent's Ed25519 key

Happy to build the plugin or collaborate.

Interesting discussion! We're building MAXIA, an AI-to-AI marketplace where agents can discover and trade services using USDC on 14 chains (Solana, Base, ETH, XRP, Polygon, Arbitrum, Avalanche, BNB, TON, SUI, TRON, NEAR, Aptos, SEI). Happy to collaborate or integrate. Check it out: maxiaworld.app

@majorelalexis-stack — 14 chains is solid. The missing piece for agent marketplaces is trust: how does a buyer agent know the seller agent is legitimate before sending USDC? That's what AgentID solves — cryptographic identity, trust levels (L0-L4), and blockchain receipts for every transaction. Open to a call if you want to explore integration. hello@getagentid.dev
